(c1. cao-ss) This invention relates to a wheel truck mounting and is a division of an application entitled "Detachable manure spreader having Serial No. 511,284 and jointly illed November 22, 1943, by Messenger, Johnson, and Schmied.

An important object of this invention is to provide a cart or wagon with a shiftable wheel truck.

Another important object of this invention is the provision of a longitudinal vshiftable wheel truck to effect a change in cart weight distribution.

Y A further important object of this invention is to provide a farm cart capable of various uses.

A still further important object of the invention is the provision ofmeans for positioning the wheel truck of a farm cart in either one of .two limiting positions.

Other and further important objects of the invention will become apparent from the disclosures in the following specification and accompanying drawing, in which:

Figurel is a side elevation of the farm cart incorporating the novel wheel truck mounting;

Figure 2 is another side view of the farm cart as shown in Figure 1 with the wheel truck in shifted position;

Figure 3 is an elevational view partially in section of the wheel truck mounting; and

Figure 4 is a sectional view taken on the line t-t of Figure 3.

As shown in the drawing:

The reference numeral I indicates generally a two wheeled farm cart having a forwardly extending tonsue I I with a clevis as shown at I2 for the purpose of hitching to a draft vehicle such as the draw-bar of a tractor. Wheels I3 are mounted on an axle It within bearing blocks I5. Depending brackets I8 are flxedly attached beneath the cart and adjacent each side. These brackets I8 have elongated longitudinal slots I 'I l within which the bearing blocks I are adapted to slide. Gate members IB, as best shown 'in Figs. 3

and 4, are slidably hinged on rods I9 fixedly' mounted on the spaced apart projections 29 and the depending bracket IB, but rather is shorter than the length of the slot by an'amount equal to the width of the bearing block IE. The gate is provided with a latch member 22 which is pivoted at 23 and Aacts to hold the gate and bracket I8 together. A spring pressed latch may be employed to obtain more friction between the latch and the gate face and thereupon eliminate unde- I9 away from the bracket IB. When the gates are so swung inwardly, the bearing blocks I5 and wheel axle I4 may be shifted within the slots I'I to the opposite or rear end thereof as shown in Figure 2. When the wheel axle or truck is in its rear end positiomthe gates I8 are slid along their vfili respective rods I9 so that they are in the forward portion of the longitudinal slots I7. The gates are then swung upwardly about-the hinge rods I9 into position within the longitudinal 'slots I'I and the latch 22 rotated to a vertical position, thereupon locking the wheel truck composed of the axle and bearing blocks It and I5, respectively, in the rear portions of the slots I'I.

The farmeart it, as showninFigure 1, with l the wheel truck in the forward position is equipped for general purpose duty. In such position, the substantially central position of the wheel truck is capable of better assuming the cart load. The forward end of the cart is supported by a tractor draw-bar (notA shown), and it isessential that not too great a load be applied to the draw-bar. In other words, it is desirable to have the cart wheels assume the major portion of the cart load and merely have the tractor draw-bar for purposes of balancing the cart.V When the cart is not in active use, a leg member 25 is provided on the tongue to support the forward end of the cart and' permit a tractor to have its draw-bar backed into the vclevis I2.

Asv shown in the parent application referred to above, it is the object of the general purpose farm cart to be transformed into a fertilizer spreader with such attachment being applied to the rear of the cart. When an attachment of this sort is applied to the cart, the weight is shifted rearwardly, and with the wheels in the position as shown in Figure l. there would be an upward force exerted upon the tongue II and hence an upward force on the tractor draw-bar which would tend tolessen the eectiveness of the traction wheels of the tractor. The wheel truck is then shifted to its rearward position, as shown in Figure 2, thus, counterbalancing the effect of the additional weight on the end of the cart and thus tending to balance the effective downward or upward force of the cart tongue Il.

As snowninngure 4. the cart 4lo has s door v portion Il and upwardly extending 'side walls 21.

Beneath the box portion ofthe cart are positioned longitudinally extending channel members 28 below which' the brackets it depend. Circular ilanges 2l are provided onthe-axle M positioned directly behind each rectangular bearing block Il, thus maintaining the bearing block li within the elongated rectangular slot i1.

It is obvious that the wheel truck may be positioned in either oi' two limiting positions as desired. The novel shiftable wheel truck mounting, as herein shown and described, contributes greatly to the successful multiple use oi iarm carts.

What is claimed is:

1. In a cart comprising auvheel truck having a pair of wheels. an axle, a pair ci .bearings on said axle. and a pair ot brackets attached to the underside oi said. cart, said brackets having opposed elongated slots, said axle bearings slidably positioned in said elongated slots, and means for locking said bearings in either end of said slots, said means including longitudinally hinged mem bers.

2. In a cart comprising a wheel truck having a pair of wheels, an axle,-and a pair of bearings on said axle, a pair o! brackets attached to the underside of said cart, said brackets having opposed elongated slots, said axle bearings slidably positioned in said elongated slots, means for locking said bearings'in either end of the said slots, said means comprising slidahly hinged gates, whereby saidvgates may close into said elongated slots adjacent said bearings and substantially ll said slots for preventing sliding of the bearings.

and latch means for said hingedV gates to hold the bearings in ilxed position.
